Abstract
A system for controlling two wheels at one end of a skid steer vehicle. The wheels are mounted at the distal ends of a pair of downwardly extending pivot arms; the pivot arms are mounted on the vehicle body about a common transverse axis. Two hydraulic cylinders can be operated simultaneously in either direction to raise or lower the ends of both the pivot arms thereby lowering or raising one end of the vehicle. The two hydraulic cylinders under another operating condition for the vehicle are interconnected through a hydraulic loop circuit which permits the wheel on one side of the vehicle to move upwardly and the wheel on the other side move downwardly the same amount to automatically change the attitude of the vehicle to a more nearly level position.
